Could of brought one or more of these off the shelf, the unit inside and the solar panel outside facing South;
LIDL Northern Ireland - lidl-ni.co.uk
Were on sale in the UK 2 wks ago @ £29.99, so no longer on UK site, although some stores may still have some ?
Selling same units at Maplins - for nearly double the price;
LED Solar Floodlight with PIR : Solar Shed Lights : Maplin Electronics
After using for a few weeks now - these unit however arent as good IMO as the mains supply 30watt LED units mentioned above, but they would be OK for internal use, which you could do.........
